“…Four different types of motors (IM [3], [4], [24], [32], [34], surface permanent magnet motor [3], [5], [26]- [30], [33], IPM [35], and SRM [23], [25], [31]) have been reported in the literature for IMD application. The IMs typically have the relatively long winding overhang, which gives extra space for power electronics for ASM, as shown in Fig.…”

An integration of an electric motor and a drive with wide-bandgap (WBG) devices possesses numerous attractive features for electrified and decentralized actuation systems. The WBG devices can operate at a high-junction temperature (>170°C) with improved efficiency due to fast switching speed and low on-state resistance. It also leads to better performance and higher power density electro-hydrostatic actuators (EHAs) than the traditional solutions, which are being widely adopted in industrial applications such as aerospace, robotics, automobiles, manufacturing, wind turbine, and off-road vehicles. This paper introduces and investigates the benefits of the integrated motor drive with the WBG-based power electronics for the EHA systems.

“…5. The compared Si and SiC chips are in completely different packages or application conditions, e.g., [12,13,14]. This makes it difficult to evaluate if the reported benefits of SiC are really coming from the advantages offered by the technology itself or simply due to the difference in package/operating conditions.…”

This paper investigates the efficiency benefits of replacing the Silicon diodes of a commercial IGBT module for the main inverter application of an electric vehicle with Silicon Carbide diodes, leaving the package, operating conditions and the system unchanged. This ensures that the comparison is directly between the chip technologies without any scope for discrepancies arising out of differences in the packaging, gatedriver circuit etc. A behavioral power loss calculation model is used to investigate the performance of the two modules for various drive cycles (Artemis, WLTP, NEDC). The behavioral power loss model is experimentally validated using two independent measurement methods, namely, power analyser based electrical input output method, and a calorimetric method which was developed especially for the low lossy light load condition. Furthermore, it is shown that the electrical method has close to 30% inaccuracy making it unsuitable for the main inverter applications, especially for comparing two different chip technologies, e.g., Silicon versus Silicon Carbide. The developed calorimetric method in contrast offers lower than 3% uncertainty.

“…Figure illustrates a practical application of an inverter consisting of a plurality of parallel‐connected capacitor cells. This type of three‐phase inverter circuit, which has a DC‐link capacitor on each phase leg, is widely used in motor drives and uninterruptible power supplies . With this configuration, each mounted unit consists of a one phase leg of a power semiconductor module and a DC‐link capacitor connected thereto.…”

This paper proposes a method to suppress the capacitor current imbalance between the phase legs of a three-phase inverter circuit. This circuit consists of half-bridge modules and DC-link capacitors closely connected to each module. It can be designed for low stray inductance between power semiconductor devices and DC-link capacitors in each module. However, in the conventional structure, the stray inductance between the phase legs may lead to an imbalance in the capacitor current due to the DC-side resonance phenomenon under a higher switching frequency condition by using a SiC MOSFET. This paper presents the analyses of the equivalent circuit considering the circuit configuration, which suggests that capacitor current imbalance occurs depending on the stray inductance between phase legs. To suppress the capacitor current imbalance, a delta-type bus bar connecting phase legs is proposed. The experiment results at 300 V and 4.6 A demonstrate the suppression effectiveness of the proposed method.
